We recently added three new hens to our flock and our sweet, well-behaved little gals have picked up a very bad habit from the new gals - they are roosting in the trees at night! Our Cochins are still tucking themselves up nicely in the coop at night, but now I've got Grand Firs filled with chickens 15 feet up! Even my bossy Rhodies are doing it now. We let ours free-forage in the backyard, so catching them and tucking them in the coop at night would be - exhausting! I'm hoping I can clip their feathers as I can catch them, man are they wiley! We're fortunate in that we don't have a lot of ground-dwelling predators around here - no raccoons, coyotes, etc. but I'm worried about owls and eagles. We're expanding the coop just in case that's the issue, considering another pen and I'm going to have our farmhand cut the lower branches off the trees. Any other ideas?
